Smart lighting has moved from a niche building automation feature to a strategic infrastructure layer for high-performance buildings, campuses, and public-realm developments. In Saudi Arabia, this shift is particularly significant because Vision 2030 links digital transformation, energy productivity, sustainable urbanism, and quality-of-life improvements to the delivery of new districts, giga-projects, and retrofit programs. This review examines how smart lighting control systems can support energy conservation across Saudi Vision 2030 developments, including residential communities, commercial buildings, institutional campuses, mixed-use districts, public space, and transport corridors. The paper is structured as a PRISMA-guided review and synthesizes peer-reviewed and institutional sources published from 2020 to early 2026. The literature screened for the review covered LED efficacy, occupancy and vacancy sensing, daylight harvesting, scheduling, addressable controls, wireless communication, Internet of Things integration, building energy management systems, digital twins, artificial intelligence, public-lighting analytics, Saudi policy frameworks, and implementation challenges in hot-arid climates. The synthesis shows that the strongest savings do not come from any single technology alone. Rather, the most credible energy-conservation pathway combines high-efficacy LED luminaires, robust commissioning, zone-level sensing, daylight-responsive dimming, adaptive scheduling, and integration with broader building or city-management platforms. For Saudi developments, climate responsiveness matters: deep floor plates, high solar exposure, glare control, dust, maintenance cycles, and the interaction between lighting, cooling loads, and occupant comfort all affect system performance. The review also finds that the value proposition of smart lighting is widening beyond operational electricity savings to include demand flexibility, maintenance intelligence, user wellbeing, urban safety, and carbon-aware asset management. Based on the evidence, the paper proposes a Saudi-oriented implementation framework that aligns lighting design, controls architecture, governance, procurement, and post-occupancy verification. The paper concludes that smart lighting is one of the most scalable and near-term opportunities for energy conservation in Vision 2030 developments, but its full impact depends on standards alignment, interoperable controls, data governance, commissioning discipline, and life-cycle decision making.
